Hamm, sadly, will appear only in Simpson-ized form and also sans skinny lapels and Old Fashioned, but we still get to hear his voice which, we suspect, is the real reason Don Draper has had such amazing success with women. Just listen to him recite "Mayakovsky", a poem by Frank O'Hara, in voiceover in the premiere episode of Season 2.

The episode will also not be a Mad Men parody. That's already been done. In the upcoming Simpsons episode, Hamm plays a gruff FBI agent who supervises Homer when Homer goes undercover in prison to infiltrate Fat Tony's inner circle.
